In the past few years, acquired demyelinating syndromes of the central nervous system associated with antibodies against myelin oligodendrocyte glycoprotein (MOG) have evolved into a new inflammatory disease entity distinct from neuromyelitis optica spectrum disorders or multiple sclerosis. The meticulous clinical description of patients with MOG IgG antibodies (MOG-IgG) has been achieved by development and use of highly specific cell-based assays. MOG-IgG associated disorders comprise a wide spectrum of syndromes ranging from acute disseminated encephalomyelitis predominantly in children to optic neuritis or myelitis mostly in adults. In recent studies, phenotype of MOG-IgG associated disorders has further broadened with the description of cases of brainstem encephalitis, encephalitis with seizures and overlap syndromes with other types of autoimmune encephalitis. In this review, we provide an overview of current knowledge of MOG-IgG associated disorders, describe the clinical presentations identified, highlight differences from neuromyelitis optica spectrum disorders and multiple sclerosis, summarize clinical outcome and concepts of immune treatment, depict the underlying mechanisms of antibody pathogenicity and provide the methodological essentials of MOG-IgG assays.

Although pediatric myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease is increasingly well-recognized, its full clinical spectrum is still being defined. Cortical encephalitis is emerging as a distinct clinico-radiologic syndrome of adult MOG antibody-associated disease. We describe a 12-year-old girl who presented with new onset seizures and left-sided hemiparesis. Brain MRI showed edema of the right temporal-parietal-occipital cortex with associated focal leptomeningeal enhancement. Patient received high-dose corticosteroids and 21 days of acyclovir despite negative infectious work-up due to the focal nature of encephalitis. Patient remained seizure-free for 20 months before presenting with new right hemiclonic seizures with right-sided hemiparesis and edema of the left temporal-parietal cortex with associated leptomeningeal enhancement. Patient's MOG antibody titer was 1:40. She completed high-dose corticosteroids and intravenous immunoglobulin. Our patient highlights the importance of MOG antibody testing in pediatric focal cortical encephalitis to avoid unnecessary anti-viral agents and provide more appropriate immunotherapy and a more informed prognosis.
